Call me paranoid, but I don't really trust any 3rd party keyword generator/analysis programs. (I think that they ALL call home to build up a data base for the creator.)
Not even Google's, because I think that they not only keep a data base of the most searched terms by consumers, but also of the terms searched for by their program and 3rd party programs when they detect them.
Then they add a higher value to the terms from BOTH sides of the search, not just the relevant consumer searches. BASTARDS!!! LOL
If anyone thinks that I'm too cynical just say so.
